To all whom: it may concern:

Be it known that I, ALFRED E. MASKREY, a subject of the King of Great Britain, residing at Canton, in the county of Stark and State of Ohio, have invented. a new and useful Pickling-Machine, of which the following is a specification.

My invention relates to improvements in machines for pickling and washing metal plates and has more especial reference to a vertical motor driven machine provided with a counter-weight for balancing the holders and fluid operated cylinders for raising the holders out of the vats.

The object of my invention is the provision of a motor driven pickling machine provided with fluid cylinders arranged to raise the holders 0r crates out of the pickling and washing vats.

A. further object is the provision of a pickling machine of this character provided with a counter-weight arranged to balance the holders or crates.

A. further object is the provision of a pickling machine of the character referred to in which a vertically reciprocating ram is provided, a spider being slidably and rotatably mounted near the upper portion of said ram, holders or crates suspended from said spider in suitable pickling and washing vats and fluid cylinders provided for vertically moving said spider with relation to the ram to elevate the holders or crates above the vats.

With these objects in View the invention consists in the novel construction and arrangement of parts, hereinafter described,

illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of construction may be made within the scope of the appended claims, without departlng from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings: Figure 1 isa top plan view of a pickling machine embodying my invention. Fig. 2 is a section on the line 2-2, Fig. 1. Fig. 3 is a section on the line 33, Fig. 1. Similar numerals of reference indicate corresponding parts throughout the several figures of the drawings.

Referring more especially to the construcings, the numeral 1 indicates a cement base which is properly'shaped to receive the pickling machine and vats and the driving mechanism. The numerals 2 and 3 representing pickling vats and the numeral 1 a washing vat within which the crates carrying the plates are successively immerged in the usual manner.

A vertical bearing 5 is centrally located upon the concrete base 1 and provided with upper and lower annular flanges 6 and 7 respectively, the lower flange 7 resting upon the concrete base and connected thereto by suitable tie-rods 8. A bushing 9 is preferably provided within the bearing 5 and mounted for vertical reciprocation therein is the ram 10 which is arranged to seat upon a suitable cushion member such as indicated at 11, springs 12 being provided to prevent any shock upon the downward movement of the ram.

A suitable cylindrical member 13 is mounted upon the flange 6 of the bearing 5 and extends to a point adjacent the upper portion of the ram, the plate 14 being carried upon the upper end of said cylinderwithin the pit 21.

The sprocket wheel 23 is connected, by

means of a pitman rod 2 1, with an arm 25 mounted upon the shaft of the worm wheel 26, which worm wheel meshes with a worm 27 mounted on the shaft 28 of the motor 29. Mounted upon the other side of the sprocket wheel 23 is a wrist pin 30 to which is connected the piston rod 31 of a fluid compressor 32, said compressor being connected by means of a pipe 33 with any suitable fluid storage tank, not shown. A. sprocket chain 34 is connected to the sprocket wheel 23 and located around said sprocket wheel, a counter-weight 35 being extended from the free extremity of said sprocket shank.

Fluid cylinders 36 are mounted upon the flange 6 of the bearing 5 and located within the cylindrical member 13, said fluid cylinders being provided with suitable pistons 37, to which are connected rods 38 extending upwardly through suitable bearings 39 formed in the plate 14. Fluid is admitted to the lower extremities of said cylinders by means of pipes 40 which extend from the fluid tank above referred to.

A head 41 is mounted upon the upper portion of the ram 10 and arranged to normally rest upon the shoulder 42 provided upon said ram, said head being arranged for slidable movement with relation to the ram and provided in its lower face with suitable sockets 43 arranged to receive the upper extremities of the rods 38. The head 41 is provided with an upwardly extending cylindrical portion 44 upon which is rotatably mounted the hub 45 of the spider 46, said spider being provided with four arms 47 from which are suspended by means of cables or their equivalents 48 the crates 49 which receive the sheets to be treated and are arranged to be reciprocated within the vats as will be hereinafter described. A suitable ball race 50 is provided between the hub 45 and the head 41 in order that the spider may be easily rotated upon the head when desired.

The operation of the machine is as follows: The parts being in the position shown in Figs. 1 and 2, the crate designated by the letter A has just been removed from the washing vat 4 and the sheets or plates removed therefrom. This crate is now in position to be refilled with sheets to be re-treated, after which air from the storage tank (not shown) is admitted through the pipes 40 to the cylinders 36, the pistons 37 being raised, the rods 38 contacting with the sockets 43 in the head 41 and raising said head the crates 49 being thus raised above the level of the vats. The spider and the crates carried thereby may then be easily rotated by hand a quarter turn in the direction shown by the arrow in Fig. 1 until the crate A is suspended above the first pickling tank 2. The crate B which has been treated in the pickling tank 2 is then suspended above the tank 3 in which a different pickling solution may be contained, the crate C which has just emerged from the pickling tank 3 is then suspended above the washing tank 4 and the crate D which has just emerged from the washing tank is moved to the emptying and filling positions occupied by the crate A shown in Fig. 1. The air is now exhausted from the cylinders 36 allowing the plungers 37 to move back to the normal position shown in Fig. 2 the crates being lowered within the vats as shown in Fig. 2. The motor 29 is then operated and through the worm and worm wheel and pitman rod the sprocket wheel 23 is oscillated thus oscillatsuspended from the sprocket wheel 23 thus balances the shaft 19, counter-balancing the crates and the sheets carried therein and not only relieving the strain from the shaft 19 but causing the crates to be more easily and evenly reciprocated. i

I claim:

1. In a pickling and washing machine of the character described, the combination with a plurality of vats, of a vertically movable ram, a rotary and vertically movable spider mounted upon said ram, crates carried by said spider and arranged to be received within said vats and means for raising and lowering said spider upon said ram.
